We're not suggesting you need help in that area, but if you do... Thingdom is a genetics game presented like a virtual pet sim, designed to teach kids mating—and how who you do it with alters babies.

There's a routine bit of foreplay first, as ever, in which you feed, stroke and play with your blob-like Thing. Then after impressing a potential mate via a mini game, it's down to business. Following a successful mating process you're presented with a few example babies, complete with an explanation of the dominant and recessive genes they inherited from their parents. Which is when it got too complicated and we stopped playing. [Thingdom via The Guardian]
